Ferrotec’s APG E Series Audio Ferrofluid

Ferrotec’s APG E-Series ferrofluids are based on the same chemistry as the APG 900 series ferrofluids so their properties are similar. However, the Eseries fluids have been tailored to meet specific requirements of a loudspeaker by altering their colloid stability or magnetization and viscosity values. These ferrofluids cover a broad range of applications due to their customized nature. An “E” type ferrofluid can be used for heat transfer alone or for heat transfer and damping. The transient temperature capacity of these fluids is 200°C, however, to ensure long term reliability, operation above 115°C for extended periods should be minimized. They are durable under high humidity and in contact with water.

Carrier Liquid: synthetic hydrocarbon
Appearance: black-brown or red-brown viscous fluid
